Im assuming you mean 2x^2-3x-9=0 ?
If so, you have to factorise the equation
(2x-3) (x+3) = 0

2x - 3 = 0
2x = 3
x = 1.5

x + 3 = 0
x = -3

x is either 1.5 or -3

Which expression is equivalent to the following complex fraction?

jekas [21]

Answer: last option.

Step-by-step explanation:

- Subtract the fractions that are in the numerator.

- Add the fractions that are in the denominator.

Then:

$\frac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}=\frac{\frac{y-x}{xy}}{\frac{y+x}{xy}}$

- Multiply the numerator of the fraction on the top by the denomianator of the fraction on the bottom.

- Simplify.

Then:

$=\frac{(y-x)(xy)}{(y+x)(xy)}=\frac{(y-x)}{(y+x)}$
